An air curtain is a device that blows a stream of air across a doorway or window when opened, to reduce heat loss or heat gain. The airstream also reduces the entrance of dirt and insects.

How It Works
The air curtain fan propels air at programmed speeds and direction, to provide a wall of air across the opening of a door or window. The air is blown at a high enough speed and thickness that prevents outdoor and indoor air from mixing. This air flow also acts as a barrier to dust, odor and insects from entering the building.
- Energy and cost savings
- Provides a consistent temperature and improved work environment
- Generally improves air quality when used in combination with a make-up air system by producing a good air mixture and reducing stale contaminated air
Air curtains are ideal for buildings that use large doors frequently. Air curtains are commonly used on openings to the outdoors or to sections of a building that are not heated that may need to remain open because of high traffic.
Typical applications include loading docks, store or office entrances, and cold storage facilities.
Air curtains require minimal maintenance. However, dust and debris can often build-up in the device and cause a drop in performance. To ensure optimum performance and noise reduction, be sure to clean the filters routinely.
